Patent DE-2856805-A1 (DE)
Title: Hydraulic pump driving IC engine fuel control system - has locking device stopping energy supply to pressure control valve
IPC: F02D29/04
Filed: 1978-12-29
Abstract: The system regulates the fuel supply to an IC engine driving a pump in a hydraulic system. The pump delivers to a variable volume consumer unit, parallel to which is a valve keeping the pressure constant and controlling an overflow pipe to the storage tank. The valve has a slide whose end face is subjected to the pressure from the fluid delivered by the pump and which is constantly loaded in the opposite direction. Thus axial movement of the slide initially throttles the fluid flow by the control edge of its end face, and with further movement shuts it off, its movement towards the shut-off position causing the engine throttle to increase the fuel supply. In the drive mechanism supplying the energy to load the slide in the opposite direction to the fluid pressure in the overflow pipe is a locking device. When a release mechanism is actuated this stops the supply of this energy immediately.

Title: Hot forging press with pivoted upper ram - comprising piston cylinder unit filled with compressed gas
Inventor: BECHE HANS DIPL ING
IPC: B21J9/06
Filed: 1979-06-16
Abstract: The hot forging press has a curved upper die which is moved by a drive, independent of the press drive, to roll a blank against a flat lower die. The upper die has a pivot axis, which can be displaced sideways, and is carried by a swinging arm, which can be pivoted about its axis and is mounted in a bearing which can be moved along a guide track in the press frame. The improvement is that the swinging arm is a piston-cylinder unit filled with gas at a pressure corresponding to the forging pressure. Pref. the piston is mounted in the bearing and the cylinder carries the upper die. Forging can be carried out immediately after insertion of the blank since the dies do not have to be raised or lowered as in conventional forging presses. The gas filling in the swinging arm acts as a buffer against press overloads.

Title: Reciprocating IC engine with water injection - has regenerative heat exchanger in exhaust valve port to raise steam to increase output
Inventor: HAEBERLE WILHELM
IPC: F02B41/00
Filed: 1979-07-04
Abstract: The engine has a piston (13) reciprocating in a cylinder (12) with an inlet valve (15) and an exhaust valve (18). A recess (31) in the cylinder head between the combustion space and the exhaust valve contains a regenerative beat exchanger (32) made of steel wool. When the regenerator has gained sufficient beat from the exhaust flowing through it, water (35,34) is injected into it (33). At the same time the inlet valve is closed and the supply of fuel shut off. The water is evaporated and the resulting steam performs useful work on the piston. When the stored heat has been used the water injection is stopped and normal operation is restarted.
